Loving the Cold: Microbes from the Archeozoic Eon

On a snowy winter day there is nothing better than sitting next to a warm fire with a hot beverage dreaming of Cayo de Aqua beaches in Venezuela; however, in reality over 80% of the Earth never reaches above 5°C (3). Even more distant from our thoughts is that many microorganisms inhabit these inhabitable landscapes […]

Antimicrobial Testing – Exceeding the Standards

Electronic Equipment – From individual components to entire assemblies, electronic equipment can present a favorable environment for microbial growth Fuels and Lubricant – Storage, use, and disposal of fuels and lubricants can be impacted by microbes, whether the need is to prevent microbial growth or to encourage microbial consumption Textiles – Used in harsh conditions […]

Biodegradation Testing and Product Claims

Raw Materials Even for naturally sources materials, biodegradation testing may be required prior to acceptance. Formulations Biodegradation is not a calculation – testing a product’s performance before deciding which formulation works as intended can potentially save a lot of time and effort down the line. Finished Products The finished product as it would be delivered […]

Personal Care Preservation & Performance Testing

Steps to Reducing and Preventing Microbial Contamination Microbial Screening Microbes can grow nearly everywhere – make sure the production lines, raw materials, and packaging are as clear as possible before filling orders Durability Testing a products performance for a specific environment. Can be heat, UV, moisture, etc; make sure to test in similar conditions, not just with standard […]

Personal Care Test Methods

Commonly requested test methods for personal are and cosmetic products include: Preservation ASTM E640 – Preservatives in Water-Containing Cosmetics ASTM E645 – Evaluation of Preservatives in Cooling Water (Industrial Water Testing) Shelf Life Accelerated Aging – Heat Accelerated Aging – Spray/Wipe Accelerated Aging – UV Exposure Accelerated Aging – Water Mist Biodegradation OECD 301B for […]

Certified Compostable Testing at Situ Biosciences

Quality Assurance has little meaning without valid testing. Compostability performance is no different. Like any other product, compostable products and their associated performance claims need to be substantiated and backed up by valid scientific test results. Based on standard industrial methods including ASTM D6400, certified compostable products assure end-customers of the quality of the product. Test progress […]

Biodegradation Testing: Challenges & Test Method Selection

Challenges Common issues include solubility, volatility and choosing the appropriate method Liquids Formulations and finished products; products likely to be disposed of down the drain or in water systems Solids Methods for packaging, plastics, and products that would be disposed of in solid waste systems Test Methods Cover a range of product types and intended […]

Biodegradation: DOC, CO2, O2 Measurements & Methods

Solutions and Liquid Testing Overview Used for determination of Ready, Ultimate and/or Inherent Biodegradability OECD 301 Biodegradation methods typically run for 28 days; OECD 302 Biodegradation Methods are intended for longer term testing; with more complicated solutions. Many other harmonized methods and variants of the OECD method exist.  The differences between these method are due […]

Biodegradation Testing for Compostable Solids

Selecting a Biodegradation Test Plastics, coated materials, and packaging that will likely end up in solid waste streams have specific biodegradation test considerations. Knowing how your product is likely to be disposed of is one important consideration in determining which test method to use. Biodegradation and composting are related but not the same – before […]
